Mightyena is not a wolf, it is a hyena based Pokemon and hyenas aren't even canines.
"It is grey like a wolf, so it is a wolf"
Wolves can also be white and black, look at Umbreon. Is it suddenly a wolf because it is black? I don't think so.
"It hunts in packs"
Hyenas are also pack hunters, in fact hyenas are very good at hunting and not always scavengers, lions are actually scavengers themselves and they steal kills from other predators.
"It has pounty ears, hyenas don't"
Ever seen what a striped hyena looks like? They are the type of hyena that Mightyena is based on. Also look at the mane, look familiar? Mightyena's mane.
"It doesn't have any hyena like features"
Apart from the ears and mane, Mightyena is known as the bite Pokemon and have powerful jaws. Oh guess what? Hyenas are very well known for having powerful sets of jaws which can crush bone.
Yes the anime makes Mightyena howl and it can learn howl but then again so can Shinx and that is a lynx Pokemon.
So sorry wolf fans, Mightyena is a hyena Pokemon and not a wolf Pokemon. You want to worship a wolf Pokemon then theres Eletrike, Manetric and the two Lycanrocs.
